Abstract
The device for measuring the capacitance of electrical wires has a first and a second measuring tube both connected to a voltage source of high frequency. The first measuring tube has a conventional length while the second measuring tube is significantly shorter. With the first measuring tube the capacitance of the wire can be measured in a conventional manner. The second measuring tube allows the measurement of local changes of the capacitance.
